COMPOSITE RAILROAD-TIE AND RAIL-FAST ENER.

Specification of Letters Patent.

Patented Aug. 5,1913.

Application filed August 15, 1911. Serial N 0. 644,078.

To all whom it may concern:

Be it known that I, GEORGE J. FLEISSNER, a citizen of the United States,residing at lVashington, in the county or lVashington and State ofPennsylvania, have invented new and useful Improvements in CompositeRailroad-Ties andRail-Fasten'e rs, of which the following is a secification. My invention re ates to composite railroad ties and railsupports and particularly to the construction of ties having. a mainbddy portion of cement or concrete.

One of the main objects of my invention is to-provide a rail tie andsupport which Shall befdurable and to this end I provide a certainamountof movement of the railchair with relation to the tie and also'-rein force the main concrete body portion with metal'side plates;

Other objects of my invention will be which is to be taken in connectionwith the acompa-nylng awings showing one embodiment thereof, in'WhichFigure 1 is a perspective view showing my railroad tie and railsupportwith a pair of rails supported thereon; Fig. 2- is a verti- Fig. 3 is alongitudinal section on the line III-III of Fig. 1.

The tie or sleeper comprises a'main concrete body portion 2, and sidereinforcing bolted together as at 5, 5. The top of the as shown, as thisshape is best adapted to resist blows and to prevent the tiefroxn'becoming Worn and chipped. Upon either side there are recesses ordepressions in the top of the concrete body to receive the metalrail-chair su ports, which comprise a base or hearing p ate 7, providedwith a central depending support 8, flanked upon either side by guideand thrust plates 10, which are movable in vertical slots in theconcretebody portion and engage the inner:

depending plates 10' take the longitudinal thrust of the rails due toany creeping or tilting actian, while the spreading or lateral thrust istaken by the portion 8, and by the lug-post 12 depending from the baselate 7. In. order to absorb ing action of the Tails 1 upon the-tie'andto give the'desirable resiliency, such as is 1511-,

the shock and pound parted by theprdinary wooden tie, I sup port therail..'supporting members upon one or m bre resilient blocks 14, whichmay be rubber orsprings and rest in a socket in the concrete body, andupon which bears the depending part 8 which constitutes in effeet aplunger, The bottom of the plate 7 is normally supported by the plunger8 slightly above the bottom ofiithe recess, in order that the shockcaused by a passingtrain may be taken by the shock-absorbing media 14;,14. Access to the latter may be had through the apertures 15 when theplates 7 have been lifted sufficiently to raise the lates 10.

The rai -chair comprises interlocking portions 16, 16 which are boltedat 17 and 18 to the supporting plate 7, and each is provided with aclamping mg -i119 which engages the rail, The rail is first placed inposition upon the chair-part 16 and the other part 16 is then forcedinto the position shown, the under-running lug 20 sliding into thecorresponding recess in the bottom of the other chair-part, and then theparts are rigidly secured by means of a'pin 20" and one or more bolts18, which can he slidinto the slotted ways in the plate 7 and in theflange of the chair-part l6 as indicated. In order to relieve the bolts17 of the lateral strain or twisting action of the rails, due to thetendency of the rails to spread, I preferablyform the lug flange at adistance above the bottom of the chair-part 16, thus providing ashoulder which bears against an extended thrust-block 21 formed upon theplate 7, and any tendency of the plate to tilt or move outwardly isresisted by the lu -post 12 depending from the opposite si .e of thecenter.

The several advantages of my invention and its superiority will now beappreciated.

The form of the tie'is adapted to resist the'strains and blows to whichit may be subjected, and the reinforcing metal plates have been utilizedin a manner to relieve the concrete and preventundue wear and shocks dueto the severe pressures and blows causedby the passing trains.

The rail-supporting and locking members are exceed'ingl rigid. andsecure," and yet the parts are simple in construction and are easi yassembled.

' lhe vparts of the tie and rail securing members cooperate in a mannerveiacieedinIgly eficient r'ailsupp'ort.

ister-9e;

Vlhile I have described in detail the construction illustrating oneembodiment of my invention, I am aware that various changes may be madetherein without departing from the spirit of my invention, and it is mypurpose to cover such modifications.

I claim 1. A railway track construction comprising a tie having aconcrete body portion and metal side plates bolted or otherwise rigidlyunited, and rail supports having means for clamping the flanges of arail and provided with depending guide and thrust extensions passingthrough sockets between the body portion and the side plates.

2. A railway track construction comprising a tie having a concrete bodyportion and metal side plates bolted or otherwise rigidly united, railsupports having means for clamping the flanges of a rail and providedwith depending guide andthrust extensions passing through socketsbetween the body portion and the side plates, and resilient buiierscarried in recesses under said supports.

3. A railway tie comprising a concrete body portion having an arched orrounded top, and metal plates extending longitudinally upon either sideof said body portion and rigidly secured together, said arched topextending above the top edges of said metal plates, and. said arched topbeing provided with recesses to receive rail-fastening means.

'4. A railway track construction, comprising a tie having a concretebody portion and metal plates bolted together upon either side thereof,said body portion having recesses each provided with a central socketand lateral downward extensions, and a railsupport having abearing-plate adapted to lie in one of said recesses and provided with aplunger and depending guide plates adapted to engage said socket andlateral extensions respectively.

5. A railway track construction, comprising a tie having a concrete bodyportion and metal plates bolted together upon either side thereof, saidbody portion having recesses each provided with a central socket andlateral downward extensions, a rail-support having a bearing-plateadapted to lie in one of said recesses and provided with a longer anddepending guide plates adapted to engage said socket and lateralextensions res ectively, a rail-chair having means for 0 am Jing theflanges of a rail, and means for etachab'ly securing said chair to saidrail support.

6. A railway track construction, comprising a tie having a concrete bodyportion and tening said chairs to said rail supports.

7. A railway track construction, comprising a tie having a concrete bodyportion and metal side plates,said body portion having recesses in thetop thereof provided withlatoral downward extensions adjacent theplates, rail supports each having a bearing plate adapted to fit in oneof said recesses and provided with depending guide-plates verticallymovable in said extensions and with an upwardly-extending thrust-block,rail chairs each provided with rail-clanniing devices and having ashoulder adapted to bear against said block, said bearing plate beingalso provided with a depending lugpost adapted to resist lateralmovement due to the spreading of the rails, and means for fastening saidchairs to said rail supports.

8; A railway track construction comprising a rail support having abearing-plate provided with an upwardly extending log or thrust-block,and a two-part rail-chair formed with interlocking parts and havingmeans for securing said parts in locked position, one of said partsbearing laterally against said thrust-block.

9. A. railway track construction comprising a rail support comprising abearingplate provided with an upwardly extending lug or lhrust-blockupon one side thereot. a

do\vnwardly-extending lug-post upon the other side, and a separableinterlocking railchair clamped on said bearing plate and bearinglaterally against said thrust-block.

10. A railway track construction compris ing a'rail support having abearing-plate provided with an upwardly extending log or thrust-block,and a.two-partrail-chair formed with interlocking parts and having meansfor securing said parts in locked position, one of said parts bearinglaterally against said thrust-block and having an extended flangeadapted to extend over said thrust-block and be secured thereto.

in testimony whereof I have hereunto setmy hand in presence of twosubscribing witnesses.
